STOP AND WASTE COCK.

SPECIFICATION forming part of Letters Patent N 0. 578,885, dated March16, 1897.

Application led February 28, 1896. Serial No. 581,177. (No model.)

To all whom it may concern:

Be it known that I, TIMOTHY J. LEAHY, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Stop and Waste Cocks;and Ido hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

My invention has reference to stop and waste cocks; and the inventionconsists in the construction, combination, and arrangement of partswhereby the cock is convertible to right or left hand use, substantiallyas shown and described, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of myimproved stop and waste cock, showing the parts set, say, as rights andas they appear when in wasting position. Fig.' 2 is a side elevationthereof at right angles to the view in Fig. l and showing the same partsin the same relation with a portion of the casing broken away to revealthe outlet-passage. Fig. 3 is a vertical central sectional elevation ofthe said parts on a line corresponding to x, Fig. 2. Fig. 4: is a viewshowing the parts set as lefts or the reverse from that shown in Figs. Iand 2. Fig. 5 is a view ot' my improved mechanism corresponding to viewlooking down from line 5 5, Fig. l, but containing a modification of theadjusting collar and the stop mechanism therefor, as hereinafterdescribed. Fig. 6 is a perspective view of still another modified formof collar, as hereinafter described.

A represents the body or casing of my improved mechanism, threaded ateach end, as usual, to make the pipe connections and provided with theusual waste-opening 2 at one side. I do not claim that there is anynovelty about this body part, as it is shown most plainly, for example,in Fig. 3, nor in the plug B in so far as it serves the usual purpose ofa plug for opening and closing the passage through the body and toprovide a waste through its own waste opening 3. These parts andfeatures of construction broadly are well known in the art.

Now it is desirable that a stop and waste cock should be easilyadaptable to a right or left hand setting, according as the place towhich it goes may require one or the other, and it is likewise desirablethat this convertible or interchangeable feature should not add i amechanism which makes a stop and waste cock thus convertible to a rightor a left hand arrangement, as one or the other may be wanted, is notbroadly new, because I have seen and known of a good many differentconstructions having this obj ect in view,and they are well known in theart; but I have never seen one which embodies the peculiarities ofconstruction or which has the advantages in operation which I claim formy invention.

Referring now again to the drawings, it will be seen, for example, inFig. 4 that the plug B has a hollow shank adapted to inserta key orL-shaped lever to rotate the same, the said leverbeing removable, sothat the collar C may be taken off and reversed to change its position,as herein described. If preferred, however, the said key-lever could betemporarily attached to the said plug, so that it would always be inplace for use, and obviously the said shank might be extended somewhatand the key-lever engaged over the same instead of into the socketthereof, as here shown, and obviously, also, there might be other meansof any available or suiiablekind employed to rotate the plug, no specialor particular means being indispensably necessary. The presentconstruction, however, has the advantage of leaving the plug a free andin- .dependent member, so that it is easily handled for turning down ona lathe and adapting the collar C on the shank thereof. This shank hasrounded corners 4, which are turned to this shape in the lathe, and thecollar O has its eye rounded at 5 in the angle of its sides to receivethe rounded edges f-l of the shank. The said collar Chas an eye 6,adapted to slip over and upon the shank 7 of the barrel B and to betemporarily fastened thereon by Y means of the set-screw 8. The saidcollar is shown in Figs. l and 4 as having two lateral projections orjaws 9 and I0, adapted to en- ICO gage an outward projection or arm 11,rigid with the body or shell A. The projections 9 and 10 are at rightangles to projection 11 and are spaced apart equal to a quarter-rotationof the plug B, that is, they limit the rotation of the plug to aquarter-turn, and the sleeve C and its projections of course turn withthe plug, and the sleeve is non-rotatable on the plug.

Now, referring to Fig. 1, it will be seen what the relation of B and Cis to the body A when the plug is in wasting position. In this caseprojection or jaw 10 is against projection ll of the body. Obviouslywhen the plug is in reversed position to turn the water on it will havea quarter-turn to the left and the jaw 9 will be down against projection1l. But suppose the parts are set as lefts, as in Fig. 4. In this casethe -bod y A is simply inverted or turned upside down, as compared withFig. l, but the same front is maintained. Now it is necessary to make aquarter-turn of the collar C to meet the change of body A or thewaste-orifice 3 will come to the bottom instead of the top when arotation of the plug to open the waste occurs. To effect this change ofthe collar C and make the change right, as well as to simplify theconstruction, I place the set-screw 8 in the angle between two of thesides of the eye G of the collar and form a threaded hole 14 for thescrew in the shank. Then all I have to do to change the device fromright to left or left to rightis to reverse the collar O and bring theset-screw 8 to its hole 14 in the shank. This always will bring theprojections 9 and 10 to the proper place in respect to arm 11 and keepthe device in operative position. The adjustment of the collar is madewhen the plug is in full-open position. I

Suppose the parts to be as in Fig. l. First turn quarter-way round tothe right, so as to bring jaw 9 down to arm 11. Then having inverted thebody A, as in Fig. et, to place the collar O on in the right way reverseit and bring set-screw 8 to hole 14, as already described. Then turn theplug so as to bring the parts to the position seen in Fig. 4, and

they are in waste position, the same as in Figs. 1, 2, and 3. Both thebody A and the collar C are reversed in this change, but while the anglehaving set-screw 8 does not have the hole 14 in the angle of the shankof the plug the sides of the eye C do change sides to opposite places bysaid angle. Hence to utilize a single hole for the screw 8 the screw andhole must be in the angles of the parts, as shown.

In Fig. 5 I show a modification of the body A in which are twoprojections l5 and 16 on the said body, which extend out laterally intothe path of the single projection 17 on the collar O. This collar andthese projections are operated like and serve all the purposes of theforegoing construction. So of the modification in Fig. G, where aT-shaped extension or projection on the collar O is shown. Thisprojectionhas lateral arms adapted to operate between twoproperly-placed 'projections on the barrel. (Not shown.) Still othermoditications might be given, but this is sufficient, and the sameprinciple runs through all of them.

In eachand all cases the screw S is necessarily at either an acute or anobtuse angle in respect'to the stop projection or projections on thecollar, and the set-screw 8 always comes to the same identical point onthe shank whether one or another of the collars is used. Obviously ifthe said shank were round and the eye round also the operation would bethe same.

The setscrew 8 further serves to retain the handle or lever G, which issocketed in the shank of the plug and retained in place by the saidscrew. This handle is always adjusted with the collar, so as to be inthe same working relation at all times, and thus asingle screw and holeanswer to fasten two parts.

That I claim as new, and desire to secure by Letters Patent, is

l. In astop and waste cock mechanisn1,the body, the plug having a singlehole for effecting locking engagement therewith, and the reversiblecollar having a screw to engage said hole, and stops on said parts tolimit the rotation ot the plug, substantially as described.

2. The body of the device having a iixcd projection to limit therotation of the plug, and the plug having a single hole in its shank forthe locking-screw of the collar, in combination with a reversible collarhaving a screw to engage in said hole, and a projection on said collarto engage the IiXed projection on the body, substantially as described.

3. The body part, the plug having a foursided shank and a single pointbetween the sides of the shank for the engaging screw, a collar having afour-sided eye to engage said shank and a set-screw in the angle betweensaid sides to lock the collar on the shank, and projections on the saidparts to limit the rotation of the plug, substantially as described.

4. Inastop and waste cock mechanism,the body hav ing a projection tolimit the rotation of the plug and the plug in said body having a singlepoint to lock thecollar thereon, in combination with a collar removablysecured on the shank of the plug and provided with Vtwo opposite checksto engage said stop and constructed to be set with the checks indifferent relations to the stop, substantially as described.

Witness my hand to the foregoing specification this 20t-h day ofFebruary, 1896'.
